Why are some mics better for vocals and others are better for instruments?
Microphones are designed for specific applications based on two main factors: the dynamic range (degrees of loud and quiet the mic needs to reproduce) and the frequency response (the way the mic responds to low frequency bassy sounds versus high frequency trebly sounds). Therefore, mics can be “voiced” to best represent the sonic requirements of a voice versus a guitar or bass. Mics for vocals also have features like built-in windscreens in the ball area that helps prevent the mic from popping from loud “p” and “b” sounds.
